KP2067-7B1 - Lincoln Electric KP2067-7B1 Contact Tip, 1/16 in Aluminum (10-Pack)

Precision Aluminum Welding with Lincoln Electric

The Lincoln Electric KP2067-7B1 Contact Tip is a specialized consumable designed to meet the unique demands of aluminum MIG welding. Welding with aluminum wire presents distinct challenges compared to steel, primarily due to the material's softness and high rate of thermal expansion. Standard contact tips often cause feeding issues or seizing when the wire heats up and expands within the bore. This 1/16 inch (1.6 mm) contact tip is engineered with precise tolerances to accommodate this expansion, ensuring smooth, uninterrupted wire feeding and consistent electrical contact.

Manufactured to Lincoln Electric's rigorous standards, these contact tips are essential for fabricators working with heavy-gauge aluminum applications. The high-quality copper alloy construction provides excellent thermal conductivity, keeping the tip cooler during extended welds and extending the life of the consumable. By maintaining a stable arc and reducing the frequency of burn-backs, these tips help minimize downtime and rework, which is critical in industrial production environments.

This product comes in a convenient pack of 10, ensuring that welding operators have a ready supply of fresh tips on hand. Regular replacement of contact tips is vital for maintaining weld quality, particularly with aluminum, where micro-arcing inside a worn tip can lead to erratic arc performance and contamination. Whether you are repairing aluminum trailers, fabricating marine vessels, or working on structural aluminum components, the KP2067-7B1 ensures your Lincoln Electric equipment performs at its peak.

Key Features:

• Optimized for 1/16 in (1.6 mm) aluminum wire.
